Last month, a Florida couple bought a Powerball ticket in a Florida grocery store with their usual numbers.  Now, they are $300-million richer.

Maureen Smith, 70, and David Kaltschmidt, 55, bought one of three winning tickets for the record $1.6-billion Powerball jackpot.  They stepped forward to claim their part of the winnings at the Florida Lottery headquarters in Tallahassee on Wednesday.

Lottery Secretary Tom Delacenserie said the couple elected the one-time payment option and will take home $327,800,000 after taxes. Their winning ticket was purchased at a Melbourne Beach Publix, using numbers they've played for 30 years. The other two winning tickets for the January 13 drawing were bought in Tennessee and California.

Kaltschmidt, an engineer, plans to retire.  Smith said they're not sure what else they'll do, but a new car and a massage may soon be in order.  "We have a lot to think about," she added with a smile.  "It's very stressful."

John and Lisa Robertson of Munford, Tennessee, cashed in their ticket last month.  The third winner has not been publicly identified yet.
